Hi fellows, Could you tell me how to plot 3d using coodinates? For example, I have the coordinates for one point is 0.2,0.3,04 and for another point is -0.3,0.3,0.1. How can I plot them in one graph and also connect the two points?

v1=[0.2,0.3 4 ],
v2=[-0.3,0.3,0.1],
v=[v2;v1];
plot3(v(:,1),v(:,2),v(:,3),'r')

line([x1 x2],[y1 y2],[z1 z2]) and you can put as many points as you want in each vector obviously

the line command works, you can simply use "view(az, el)" to see the 3d plot. where (AZ,EL) = view returns the current azimuth and elevation. e.g. try view(30,10) after the line command. clc clear x = line([0 1],[0,0],[0,0],'color','r'); y = line([0 0],[0,1],[0,0],'color','g'); z = line([0 0],[0,0],[0,1],'color','b'); view (30,30) grid on

or use
rotate3d on
to drag the axes freely
